Horsepower is addicting. Chances are, you've owned your Evo X for a while and you love everything about it. We dont blame you, it's a wonderful car. But there is one design flaw in the 4B11T powerplant that we've become aware of the longer the car has been in production, and we've got a revolutionary new product that is produced with stock frame turbo owners in mind. That is the MAPerformance Stainless Steel Manifold.

Drawing from our porting and tubular exhaust manifold design experience, we've invested countless man hours into research and development of this manifold including 3D rendering, virtual flow testing, rapid prototyping, and bench testing to confirm that we have produced the best possible product for our customers.

Do you know if your OEM exhaust manifold is cracked? Not many do, and it could be robbing you of power and decreasing the life of your turbo. As one of the most popular resources for ported OEM exhaust manifolds, we have seen our fair share of Evo X Manifolds. As of late, we've gotten quite a few cracked manifolds that were presumed to be in good shape. It has become incredibly hard to find a replacement OEM exhaust manifold without a crack in the collector.

Yielding an astounding 22% average increase in exhaust flow over the OEM exhaust manifold and less imbalance this manifold will produce more power, something stock frame lovers are sure to appreciate.

• Investment Casted 310s stainless steel construction. This form of casting is stronger and cleaner than sand casting, and produces some of the smoothest runners possible.

• Provisioned to allow usage of the factory heat shield. A very important feature for you stock appearing or stock frame guys and gals!

• Includes two allen head bolts to ease installation of the manifold to cylinder head.

Manifold Benefits:

• Performance. Increased exhaust flow and reduced imbalance between the runners will improve spool characteristics and produce more power.

• Durability. Constructed from 310s stainless steel and investment casted to withstand cracking in the most demanding high temperature environments.

• Stealth. Whether it is your own personal desire to keep your upgrades on the down low or motivation from an external source you can simply install the factory heat shield and onlookers will be none the wiser.

I just now saw this post, so it looks like I missed the cut. What's your price for port and polish? Any performance boost with this? I was just looking at your EF2.5 w/ your Rev 2/3 intake manifold this morning: these together with your new exhaust manifold would make a nice "package!"

We're still working on a price for porting, it will be dependent on how much time we spend on the process; I will update you as soon as it becomes available.

In regards to performance gains we are very happy with the fit and finish of the manifold out of the box. While porting certainly won't hurt we do not feel that the gains will be as substantial as our OEM porting service.
